The Effect of Environment on Type Ia Supernovae in the Dark Energy Survey Three-Year Cosmological Sample
L. Kelsey, M. Sullivan, M. Smith +73
Analyses of type Ia supernovae (SNe Ia) have found puzzling correlations between their standardised luminosities and host galaxy properties: SNe Ia in high-mass, passive hosts appe…
Shadows in the Dark: Low-Surface-Brightness Galaxies Discovered in the Dark Energy Survey
D. Tanoglidis, A. Drlica-Wagner, K. Wei +67
We present a catalog of 23,790 extended low-surface-brightness galaxies (LSBGs) identified in from the first three years of imaging data from the Dark Energy Survey…
Dark Energy Survey Year 1 results: The relationship between mass and light around cosmic voids
Y. Fang, N. Hamaus, B. Jain +74
What are the mass and galaxy profiles of cosmic voids? In this paper we use two methods to extract voids in the Dark Energy Survey (DES) Year 1 redMaGiC galaxy sample to address th…
Dark Energy Survey Year 1 Results: Joint Analysis of Galaxy Clustering, Galaxy Lensing, and CMB Lensing Two-point Functions
T. M. C. Abbott, F. B. Abdalla, A. Alarcon +164
We perform a joint analysis of the auto and cross-correlations between three cosmic fields: the galaxy density field, the galaxy weak lensing shear field, and the cosmic microwave…
Survey geometry and the internal consistency of recent cosmic shear measurements
M. A. Troxel, E. Krause, C. Chang +76
We explore the impact of an update to the typical approximation for the shape noise term in the analytic covariance matrix for cosmic shear experiments that assumes the absence of…
Dark Energy Survey Year 1 Results: Methodology and Projections for Joint Analysis of Galaxy Clustering, Galaxy Lensing, and CMB Lensing Two-point Functions
E. J. Baxter, Y. Omori, C. Chang +91
Optical imaging surveys measure both the galaxy density and the gravitational lensing-induced shear fields across the sky. Recently, the Dark Energy Survey (DES) collaboration used…
